What is caulk?
Caulk is a type of finishing material that is used to fill in gaps, cracks, and breaks in various surfaces. By using caulk, you can help to prevent heat loss around windows and doors, water leakage around toilets and bathtubs, and cracks in your driveway and foundation. Sometimes referred to as sealant, caulk used to only be available in polyurethane and silicone forms. However, there are now a variety of different types of caulk specifically designed for a number of different home repair jobs. Choosing Your Caulk When it comes time to choosing a caulk for a particular repair job, it is important to consider a few key factors first. These factors will play an important role in helping you to decide what type of caulk to choose: • Indoors or Outdoors? Some caulks are designed for outdoor use, while others work better inside the home. Depending upon your job, you may need an inside or outside caulk. • Temperature: Consider the temperature in the place where you are going to put the caulk
